On a sauna structure

Abstract

A sauna includes an upright wall, a base, and a top; the upright wall includes posts each having two lengthways extending grooves, and cavities; the wall has transverse rods, which have tenons fitted into the cavities of the posts, and which have grooves; the wall has panels, which are fitted in the grooves of the posts and the transverse rods at edges; the base and the top are joined to lower and upper ends of the wall, and each include a frame having one inward circumferential groove, and cavities; panels are fitted in the grooves of the frames at edges, and supported with longitudinal and transverse rods, which have tenons fitted in the cavities of the frames; the longitudinal and the transverse rods have spaced gaps; the longitudinal rods are fitted in the gaps of the transverse rods; the transverse rods are fitted in the gaps of the longitudinal rods.

1 . An improvement on a sauna structure, comprising 
 (a) an upright wall, said upright wall including:    a plurality of upright posts, each of said upright posts having two grooves on a lateral side; each of said upright posts having a plurality of fitting cavities on lateral sides thereof;    a plurality of transverse rods, each of said transverse rods having a plurality of tenons on two ends, which are fitted into said fitting cavities of said upright posts; each of said transverse rods having grooves thereon; and    a plurality of panels, said panels being fitted in said grooves of said upright posts and said grooves of said transverse rods at edges;    (b) a base joined to a lower end of said upright wall; and    (c) a top joined to an upper end of said upright wall;    each of said base and said top including:    a frame, said frame having at least one groove on an inner side thereof, and a plurality of fitting cavities thereon;    a plurality of panels, said panels being fitted in said groove of said frame at edges thereof;    a plurality of longitudinal rods supporting said panels, said longitudinal rods having tenons on first and second ends thereof; said tenons of said first ends of said longitudinal rods being fitted in said fitting cavities of said frame; said longitudinal rods having a plurality of fitting gaps; and    a plurality of transverse rods supporting said panels, said transverse rods having tenons on first and second ends thereof; said tenons of said first ends of said transverse rods being fitted in said fitting cavities of said frame; said transverse rods having a plurality of fitting gaps, in which said longitudinal rods are fitted; said transverse rods being fitted in said fitting gaps of said longitudinal rods.    
   
   
       2 . The improvement on a sauna structure as recited in  claim 1 , wherein each of said upright posts has tenons on two ends thereof, which are fitted in said fitting cavities of said base and said top.  
   
   
       3 . The improvement on a sauna structure as recited in  claim 1 , wherein said upright wall has a pair of upright posts on each corner thereof; a first one of said upright posts has a groove, and a second one of said upright posts has a strip-shaped fitting protrusion, which is fitted in said groove of said first upright post.  
   
   
       4 . The improvement on a sauna structure as recited in  claim 1 , wherein each of said base and said top has a beam, which has tenons on two ends thereof, and has a plurality of fitting cavities, and is fitted in said fitting cavities of said frame; corresponding ones of said tenons on said second ends of said longitudinal rods and said transverse rods being fitted in said fitting cavities of said beams.  
   
   
       5 . The improvement on a sauna structure as recited in  claim 1 , wherein said top has a head plank secured thereto, and the base has a threshold plank secured thereto; said head plank and said threshold plank having pivotal holes; a door plank being pivoted on said pivotal holes with pivotal post-shaped parts thereof being inserted in said pivotal holes of said head plank and said threshold plank.  
   
   
       6 . The improvement on a sauna structure as recited in  claim 1 , wherein said panels of said upright wall has a hole, and a control panel is fitted on said hole, and connected to infrared tubes.  
   
   
       7 . The improvement on a sauna structure as recited in  claim 1 , wherein said base and said top have decorative plates, which extend over said transverse rods of said upright wall so as to enhance connection of said upright wall with both said base and said top.  
   
   
       8 . The improvement on a sauna structure as recited in  claim 1 , wherein said upright wall has a plurality of strengthening rods between said transverse rods, and sandwiched between said panels; each of said transverse rods having fitting cavities thereon; said strengthening rods having tenons on two ends thereof, which are fitted into said fitting cavities of said transverse rods.  
   
   
       9 . The improvement on a sauna structure as recited in  claim 1 , wherein said frame of said base has a plurality of fitting cavities on an upper side thereof, and said transverse rods of said upright wall have fitting cavities on bottoms thereof, and tenons are fitted in said fitting cavities of said transverse rods of said upright wall and said frame of said base to join said transverse rods and said base together.  
   
   
       10 . The improvement on a sauna structure as recited in  claim 1 , wherein said frame of said top has a plurality of fitting cavities on a lower side thereof, and said transverse rods of said upright wall have fitting cavities on upper sides thereof, and tenons are fitted in said fitting cavities of said transverse rods of said upright wall and said frame of said top to join said transverse rods and said top together.  
   
   
       11 . The improvement on a sauna structure as recited in  claim 1 , wherein each of said top and said base has through holes, and guide grooves communicating with said through holes, and said upright posts of said upright wall have trenches extending from upper ends to lower ends thereof and communicating with said through holes of said base and said top for receiving wires therein.
